In commemorating the 2005-2006 Lewis and Clark Bicentennial in Montana, the Montana Governor’s Bicentennial Commission provided funding to various entities across the state to develop and install Wayside Interpretive Signs along the Lewis and Clark National Historic Trail in Montana. The Commission granted $50,000 to the Lewis and Clark Trail Heritage Foundation to establish a grant program to help maintain the signs that were installed during the Bicentennial. This fund has been established and is called the Lewis and Clark Bicentennial Montana Interpretive Sign Maintenance Fund.
